What is an Incident Response Plan? Modern-day enterprises experience cybersecurity threats and risks are a part of everyday business. Therefore, protecting business assets requires pre-emptive and proactive measures, and IRP is one such approach that assists security teams in handling a security event. A network security breach can put an enterprise into chaos. A security breach exposing sensitive data and networks pushes security teams into panic, especially the inexperienced ones. Even an expert security team might fail in neutralizing a threat optimally if they are unprepared. To ensure optimal handling of threats even in crunch situations, irrespective of the teams’ experience, the Incident Response Plan (IRP) comes in handy. An Incident Response Plan is a document that assists IT and OT security professionals in responding effectively and timely to cyberattacks. The IRP plan includes details, procedures, and tools for identifying, and detecting an attack/malfunction, analyzing, determining its severity, and mitigating, eliminating, and restoring operations to normalcy on IT, IIoT, and OT networks. The IRP plays a crucial role in ensuring an attack does not recur. The amalgamation of IT, IIoT, and OT networks has made cyberattacks at the core of security breaches, along with other challenges like modification to control systems, and restricting interface with operational systems among others. Attacks on IT, IIoT, and OT Networks: Cyberattacks: The cyberattacks can originate in the following manner, targeting the corporate and operational divisions of an enterprise: Modification to control systems: From disabling safety sensors to triggering a reaction of event failures, modification to control systems can have drastic effects. The case is worse in the case of OT networks, where there is little to no security with a single event capable of impacting the whole supply chain ecosystem. The physical infrastructure at manufacturing plants comprises thousands of PLCs, multi-layered SCADA systems, and DCS. Any process malfunctioning and anomalies occurring at the plant level can affect the OT infrastructure. The following signs raise red flags about malfunction or an attack on an OT network: It is crucial to acknowledge that threats can take any form and shape, and a comprehensive IRP should be able to address the challenges above thoroughly. There have been numerous instances of a cyberattack-led attack destroying OT networks and affecting related infrastructure. IRP reflects an organization’s personal and corporate information integrity. Often, many IRPs include defining roles and responsibilities, establishing communication channels between teams (IR team and the organization), and carrying out standard protocols during a security event. An Incident Response Plan continues functioning even after handling a security event effectively. It provides a window into historical data, helping auditors ascertain the risk assessment process. Evaluating the effectiveness of IRP A set of metrics need to be established to track the effectiveness of an IRP. A few of the metrics are as follows: These metrics help understand and estimate the risk weighing on the IRP and pave the way to improve it further. Importance of Incident Response Plans in IT, IoT, & OT establishments Technology and automation are woven into our daily lives. Industrial plants run on integrated and sensitive IT and OT networks, pushing the world forward. However, the evolution of IIoT has added another layer of complexity, calling for stricter security measures, given its level of social, government, and military penetration. Need for Incident Response Plan in IT & IoT A security event has the muscle to the shake foundations of businesses. The highly publicized 2015 Target data breach saw the CEO getting fired. In addition, numerous SMBs (Small and Medium Businesses) went bankrupt after a data breach was made public. Unauthorized access hampers an enterprise’s IT ecosystem and affects every device on the network, putting thousands of IoT connected to the breached IT network. It is not possible to completely secure a given IT & OT network from cyberattacks. In such an atmosphere, IRP can help minimize the damage to a good extent. It minimizes the threat radius and can help recover the systems at a swift pace. Alongside this, it plays a crucial role in meeting numerous industry and government compliances, protecting the company’s brand, and paving the way for agencies to better collaborate in tackling the threats. Need for Incident Response Plan in the OT Sector A robust Incident Response Plan in manufacturing, pharmaceuticals, and energy sectors where IoT, IIoT, OT, ICS, and SCADA systems are vital is indispensable. OT networks are the backbone of modern society, and any lapse in their functioning can have cascading effects. Given the quantum of resources (human and other assets) and the inter-dependency of additional infrastructure in OT networks, the stakes are quite high. Hence, it is important to understand why IRP plays a key role in defining the security of IIoT and OT, thereby shaping society. The past learnings are incorporated into the IRPs, making them dynamic and living processes. By having an incident response plan, organizations can learn from past incidents, conduct post-incident analyses, and continuously improve their security posture to protect their systems and assets better. Drafting an efficient Incident Response Policy for OT, IoT, and IT Networks Irrespective of the size of the enterprise, an effective Incident Response Policy is the need of the hour amid the snowballing cybersecurity threats. A comprehensive and efficient IRP helps respond to a cybersecurity incident, malfunction, or any mishap during the operational course effectively and minimize the consequential situation arising. Therefore, following strict measures while drafting an efficient Incident Response Policy is obligatory. Break down of NIST CS IR Team Incident Response Plan – OT & IT Infrastructure The Incident Handling Guide from NIST (National Institute of Standards and Technology) proposes a four-section phase for a successful IPR. It involves: Preparation phase: The initial phase of the Incident Response Plan deals with the prevention of threats arising from various reasons and causes. At this phase, most threats are flagged, dealt with, and analyzed to evaluate the extent of threat they pose to the enterprise. The threats that meet specific criteria based on threat intelligence inputs and other

The Need for OT Security Training The frequency and sophistication of cyberattacks targeting OT systems have increased significantly in recent years. According to CISA, the energy, manufacturing, and water sectors are particularly vulnerable due to their reliance on OT systems​​.  According to the National Institute of Standards and Technology (NIST), proper training helps organizations identify vulnerabilities, implement security controls, and respond effectively to incidents (NIST Special Publication 800-82, 2015).  Notable examples include the attack on water controllers in Israel and the ransomware incident at Brunswick Corporation, which disrupted manufacturing operations. The Department of Energy (DOE) also stresses the need for ongoing education to keep pace with evolving threats in the energy sector (DOE Cybersecurity Capability Maturity Model, 2022). The United States, Germany, and the United Kingdom reported the highest number of breaches, underscoring the global nature of these threats.  By investing in OT Security Training, organizations can better protect their assets, ensure operational continuity, and comply with regulatory requirements.
